Abstract: The process includes (a) mixing a titanium hydride powder having a particle size of ≦150 &mgr;m with alloying metal powders (master alloys or elemental metal powders) having a particle size in the range of {fraction (1/15)}-⅖ of the maximal particle size of titanium hydride powder, (b) compacting the resulting powder mixture by molding at the pressures of 400-1000 MPa, (c) heating up to the sintering temperature of the predetermined alloy composition at variable pressures in a furnace chamber: initial heating to 400° C. in vacuum of less than 10−2 Pa, then, heating to a temperature range of 400-900° C. with the pressures up to 104 Pa, which is controlled by hydrogen being emitted by the decomposition of titanium hydride contained in the compacted powdered alloy, and finally, heating to over 900° C. to the sintering temperature at the pressure continually decreasing to the starting vacuum level, and (d) sintering.

Abstract: The cost-effective titanium powder is manufactured by (a) magnesium-thermic reduction of titanium chlorides characterized by the formation of a hollow block of the reaction mass having an open cavity in the center of the block, (b) thermal-vacuum separation of the hollow block from excessive Mg and MgCl2 at 850-950° C. and residual pressure of 10−2-10−3 mm Hg, (c) cooling of obtained titanium hollow block in a H2-contained atmosphere at an excessive hydrogen pressure, (d) crushing the hydrogenated titanium block, (e) grinding the crushed titanium pieces into the powder combined with a hydro-metallurgical treatment of obtained titanium powder in a diluted aqueous solution of at least one chloride selected from magnesium chloride, sodium chloride, potassium chloride, or titanium chloride, and (f) drying and, optionally dehydrating the titanium powder ground to a predetermined particle size.
